17 Claims.

This invention relates to new and useful improvements in tabularbroaching machines.

One object of the invention is to provide an improved machine forpunching or notching type 5 bars, slugs and rules, which are adapted toreceive inserted column rules of the so-called linotabler form, saidmachine being constructed of a minimum number of parts which not only reduces the cost of manufacture but also facili- 10 tates its'operation.

An important object of the invention is to provide an improvedb-roaching machine wherein the supports on which the punches of themachine are mounted may be moved and adjusted 15 to their properpositions without the use of spacing members or sleeves, whereby thetime necessary to properly set the supports is minimized; said supportsalso being arranged to be moved or adjusted after the punch assembly ismount- 20 ed in the machine, whereby removal of said assembly is notnecessary to change the position of one or more of the punch supports inthe event its misadjustment is discovered after said assembly is inposition within the machine.

5 Another object of the invention. is to provide improved means forquickly and positively looking the punches and their supports againstmovement within the broaching machine, so as to assure proper punchingor notching of the type 30 bar or rule.

An important object of the invention is to provide a punch unit whichwill not bend or injure the printing face of the rule.

A further object of the invention is to provide 35 an improved means foroperating the punches of the machine, said means being so constructedthat a direct vertical or downward force parallel to the vertical axisof the punch is exerted against each punch, whereby the power neces- 4sary to operate the punches is greatly reduced and more efficientpunching or notching of the rule is had.

Still another object of the invention is to provide an improved machineof the character dea; scribed, having means for receiving type bars orrules of various widths and also having a receptacle for receiving thepunchings or cuttings, whereby the latter do not accumulate on theworking surface or board and interfere with the g operation of themachine.

A particular object of the invention is to provide a movable gage bar onwhich the rule to be punched or broached is supported in the machine,with means for locking said bar in any '55 desired position withrelation to the punches,

whereby the rule may be moved and punched any number of times withoutchanging the setting of the punches.

A construction designed to carry out the invention will be hereinafterdescribed, together with 5 other features of the invention.

The invention will be more readily understood from a reading of thefollowing specification and by reference to the accompanying drawings,in which an example of the invention is shown, and wherein:

In the drawings, the numeral ll] designates a base plate which issubstantially rectangular in shape. A supporting frame A is mounted onthe base and includes upwardly extending standards H which are locatedone at each end of the frame. The standards are mounted at the rearportion of the base (Figures 5 and 6) and are connected together neartheir lower ends by a longitudinal connecting member i2. A horizontalplatform or deck 13 is preferably made ,integral with the lower end ofthe standards and overlies the base 30, being spaced therefrom as shownin Figure 5. The platform or deck has a depending flange is around threesides thereof and the lower end of this flange engages the base tosupport; the platform and to form an enclosed chamber l5 below theplatform. The inner end of the platform or deck i3 is upset at l6 sothat its top lies in substantially the same plane as the top of theconnecting member [2 and said member and platform have their edgesspaced from each other to provide a longitudinal passage or space Htherebetween.

A longitudinal groove I8 which is substantially square in cross-sectionis formed in the top of the upset portion of the deck or platform l6 andextends substantially throughout the length thereof. A longitudinal gagerod l9, which is square in cross-section, is slidable within the grooveand has one end extending from said groove. The underside of the gagerod has teeth 20 thereon forming a gear rack which rack is adapted toengage a worm 2! (Figure The worm is keyed or otherwise fastened on astub shaft 22 journaled in one end flange 14 of the deck [3 and a knob23 is secured on the outer end of the shaft to facilitate rotation ofthe shaft and worm. Manifestly, when the worm is rotated the gage rod I9is moved within the groove 18. In some instances, it may be desirable tomove the rod manually instead of by means of the worm and for thisreason, the worm is formed with a notch 24 in its periphery. The notchis of suflicient width to permit the rod to slide therethrough, wherebywhen said notch is in registration with the gage rod, said rod may befreely moved in the groove H3. The top of the rod has graduationsthereon to designate the movement of the same, while its extreme outerend is formed with an upwardly extending integral block or lug 25, thepurpose of which will be hereinafter explained.

A longitudinal supporting bar 26 is fastened on the upset portion 16 ofthe deck by screws 21 which have their heads countersunk in said bar.The bar extends substantially throughout the length of the deck I3 andits outer end overlies the groove IE to retain the gage rod l9 withinsaid groove. The inner longitudinal edge of the bar is bevelled inwardlyas shown at 28 in Figures 5 to 8, and the extreme edge of the sameoverhangs the space I! between the connecting member l2 and deck 13.

A punch assembly B is adapted to be mounted within the frame A andincludes a pair of end supports 29. The rear lower end of each supporthas an arcuate recess 30 therein, as is clearly shown in Figure 13,while the forward lower end thereof is bevelled outwardly at 363. Alongitudinal screw-threaded shaft 3! has its ends secured to thesupports 29 and the length of the frame and deck, whereby when theassembly is in position within the frame, the end supports are locatedadjacent the inner sides of the standards I l. A square brace rod or bar32 extends between the supports and is spaced below the shaft 30. Aplurality of circular nuts 33 are threaded on the shaft 3i andobviously, by rotating said nuts, their position on the shaft may bevaried. Each nut is formed with a peripheral groove and is arranged tosupport a punch C.

Each punch includes a body or housing 35 which is substantiallyrectangular in cross-section. The lower rear end of the housing isextended and this extension is formed with an arcuate recess 36 in itsrear edge, said recess being exactly of the same curvature as therecesses 30 in the end supports 29. The upper portion of the housing isprovided with an integral rearwardly extending curved arm 37 (Figure 9)which is adapted to engage within the groove 34 of one of the supportingnuts 33. A vertical bore 38 extends through the casing and a blade 39 ismounted to slide vertically through the bore. The lower end of the bladeis substantially triangular in cross-section so that upon passingthrough a type slug or rule, a triangular opening or notch is formed.

The lower outer end of the casing is recessed as shown at 39, saidrecess having inclined walls and extending inwardly beyond the bore 3'1,

whereby the punch blade 39 moves transversely of the inner portion ofthe same. A relatively small notch 40 is provided at the base of therecess 39' as is clearly shown in Figure 9.

The punch assembly B has the grooved nuts 33 adjusted to their properposition on the shaft 3! in accordance with the spacing between thenotches to be punched. The end supports 29 which carry the shaft 3| arethen placed on the longitudinal connecting member E2 of the frame sothat the bevel 39' on the lower end of each support engages beneath thebevelled inner edge 28 of the bar 26 which is secured to the deck 13.The punches C are then placed in position, each punch having the bottomof its housing 35 resting on the member 2 with its curved arm 37engaging within the peripheral groove 34 of one of the supporting nuts33. As is clearly shown in Figures 6 to 8, the arm is confined betweenthe nut and the longitudinal rod 32 whereby vertical displacement of thehousing is impossible. When the arm 37 of the punch is engaging thegrooved nut, the lower wall of the recess 39 in the housing engages thebevelled edge 28 of the bar 26, to further prevent upward displacementof the punch.

For locking the end supports 29 and the punch housings 35 in thepositions above described, a longitudinal roller 4! is mounted withinthe standards I I. This roller is eccentrically mounted on studs 42which are journaled in the standards, and has a portion thereof cut awayto form a flat side 4!. A hand knob 43 is secured to one of the studsand is located on the outer side of one of the standards, whereby theroller may be manually rotated.

Normally the roller is in the position shown in Figure 5 so as to permitthe insertion of the punch assembly A and punches C. When said assemblyand punches are in position, the studs are rotated to impart rotation tothe roller 4|. Due to the eccentric mounting of said roller on thestuds, the rounded portion of the roller is swung into engagement withthe arcuate recesses 35 of the punch housings 35 and with the similarrecesses 30 of the supports 29. Thus, the punches and supports arepositively confined within the frame between the roller 4| and thebevelled edge 28 of the bar 26, as is clearly shown in Figures 6 to 8.

The metallic rule 44 (Figure 8) which is to be punched by the blades 38,is laid on the bar 25 and the inner longitudinal edge of the rule, whichis reduced, is engaged in the notch 40 at the base of the recess 39 inthe housing 35. The rule is firmly held in this position by a retainingbar 45 which engages the outer longitudinal edge of the rule. Theretaining bar is secured to the outer longitudinal edge of the bar .26by screws 46 which pass through the retaining bar and are threaded intothe supporting bar 25. Flat arcuate springs 47 are interposed betweenthe edge of the bar 26 and the retaining bar and exert their pressure tonormally hold said retaining bar in the position shown in Figures 5 to8, with the retaining bar in a substantially vertical position. Byloosening or tightening the screws 46, the space between the edge of thebar 26 and the retaining bar may be readily varied so that rules 44 ofvarious widths may be inserted between the retaining bar and the punchesC. Set screws 48 are provided for locking the screws 46 in any position.To permit swinging of the retaining bar 45 so as to allow thepositioning of the rule 44, the bottom of the bar is bevelled at 44' andan outwardly extending handle 49 is secured to the outer side of theretaining bar. By depressing the handle the bar 45 is swung as shown bydotted lines in Figure 6 and the rule 44 may be readily placed inposition on the bar 25, with its inner reduced end engaging the notches43 in the base of the recesses 39 of the punches C. It is noted thatwhen the rule is. in position one end thereof rests on a shoulder 25'formed on the upwardly extending block 25 of the gage rule (Figures 2and i).

From the foregoing, it will be seen that the punch assembly B is firstproperly adjusted and then locked in position within the frame. The rule44 which is to be punched or broached is then placed in position on thebar 25, with its inner longitudinal edge located within the recess 39and notch 43 of each punch. Since the recess 39 in each punch housing 35extends inwardly beyond the vertical bore 3'! in said housing, it ismanifest that the inner longitudinal edge is in alinement with saidbore. Of course, at this time, the punch blade 33 is in its raisedposition as shown in figure 6.

In order to broach or punch the rule 44, the blades 38 of the variouspunches C must be moved downwardly so that their lower ends pass throughsaid rule. For simultaneously imparting vertical movement to the blades38 of all of the punches C, a longitudinal actuating member 53 ismounted between the upper ends of the standards II. This member has itsinner end formed with ears through which a longitudinal shaft 52 extends(Figures 5 and 11) and said ears are keyed on the shaft. Each end of theshaft extends through a cylindrical head 53 which is rotatable within anopening 54' provided in the standards II. The shaft is mounted offcenter or eccentrically of the heads 53 and manifestly, when the headsare rotated, an eccentric motion is imparted to the shaft 52 andactuating member 50.

Tofacilitate rotation of the head 53, a hand knob 54, of greaterdiameter than the head, is preferably made integral with one of saidheads. As is clearly shown in Figures 1 and .11, the knob is located onthe outer side of the standard II, with its inner surface engaging saidstandard.

A longitudinal, inwardly extending keeper or flange 55 is formed on theunderside of the member 53 at its outer longitudinal edge portion andthis keeper is adapted to engage beneath a shoulder 38' provided at theupper end of each punch blade 38, as will be explained. For swinging themember 55 to rotate the shaft 52 within the head 53, a handle 55 issecured to member 50 and extends outwardly therefrom.

While the punch assembly B and the rule 44 are being placed within theframe, the actuating member 50 is in the position shown in Figure 5,having been moved to this position by swinging the member upwardly andby rotating the knob 54 and heads 53. The member is held in thisposition by the engagement of a spring pressed ball 51, which is mountedin the standard H,

with a recess 58 formed in the inner surface of the knob 54.

After the punch assembly and rule are in place, the knob 54 is rotatedso as to impart an eccentric motion to the actuating member 50, whichmotion moves the same upwardly and forwardly to the position shown indotted lines in Figure 6. The member is then swung downwardly by meansof the handle 56, the keeper or flange 55 clearing the shoulder 38' onthe upper end of each punch blade 38. Continued rotation of the knob 54and head 53 moves the keeper beneath said shoulder, as shown in Figure6, and when in this position, a second recess 59 in the head 54 isengaged by the spring pressed ball 51 to frictionally lock the head 53.

Continued downward movement of the handle causes the member 56 to movedownwardly with the shaft 52 rotating within the head, whereby the punchblades 38 engaged by the member are depressed to punch or breach theinner longitudinal edge of the rule 44, thereby forming notches 44therein. It is pointed out that due to the engagement of the outer endof member with the top of the punch blades, a direct vertical downwardthrust is exerted on the blades. This makes for easier operation of theblades during the broaching operation. As the member 50 is again swungupwardly the keeper 55 engaging beneath the shoulder 38' of each blade38, raises the blades. To remove the punch assembly B, it is onlynecessary to return the member 55 to the position shown in Figure 5 andto rotate the roller 4! to disengage the same from the assembly.

The punch blades operate directly over the space I! provided between theconnecting member i2 and deck [3 and the punchings or material cut fromthe rule 44 fall into the chamber i5 between the deck and base "I. Thesepunchings are thus prevented from falling on the deck and areefiiciently disposed of so that they do not interfere with the placingof the rule upon the next operation.

As before pointed out, the rule 44 rests on the bar 26 and has its endresting on the shoulder 25 of the block 25, which block is a part of thegage rod l9. In many instances, it may be desirable to punch the rule 44twice, with the notches 44' being spaced exactly the same distance uponthe second punching as upon the first operation. In such case, the rodl9 may be moved outwardly a desired distance by means of the worm 2!,the graduations on said rod assuring accurate movement. The movement ofthe rod and rule will thus change the position of the rule with relationto the punches and per mit a second punching operation to be performedwithout changin the adjustment of the punches. The gage rod alsofacilitates the punching of a particularly long rule.

It is pointed out that the mounting of the punches C on the adjustablenuts is an important feature of the invention. The threads on the shaft3| may be such that one complete revolution of the nut 33 will move thesame longitudina-lly a predetermined distance, as for example sixpoints. If desired, the periphery of each n'ut may have markings orgraduations thereon (Figure l3) each mark representing a given number ofpoints. With such arrangement, adjustment of the nuts 33 to their properpositions is facilitated. If the assembly B is mounted within the frameand one of the nuts 33 is found to be misalined, it may be readilyadjusted to a proper position without removing said assembly. Theprovision of said nuts threaded on the shaft entirely eliminates the useof spacing members, such as sleeves, slugs, collars and the like andgreatly simplifies the adjustment and further minimizes the timenecessary to obtain the proper adjustment.
